Who invented dry cleaning and how does it work?

Answer 1

According to Wikipedia:
"Dry cleaning uses non-water-based solvents to remove dirt and stains from clothes. The potential for using petroleum based solvents in this manner was first discovered in the mid-19th century by French dye-works owner Jean Baptiste Jolly, who noticed that his tablecloth became cleaner after his maid spilled kerosene on it, and from this observation developed a service to clean other people's clothes in this manner, which he termed 'nettoyage a sec,' or 'dry cleaning' in English."
